read data from a file

I have a data file like this:

A B C D
1 2 3 4
2 3 3 34
: : : :
: : : :
* * * *

I want to read these number and assign them to some variables, something like:

1st time:
var1=1, var2=2 var3=3, var4=4
then do something with these Var*
then 2nd time
var2=2, var2=3, var3=3 var4=34
then do something....

and so on.

How to do it in C shell script?

Thanks.
